Hi. I noticed mobygames has pictures of cd versions of both Thr Island of Dr Brain and Larry 5. Does anyone know if these are any different than their floppy versions? If you own one of these, I would be grateful if you could provide me with the version number:)

They are the same. Same version numbers, same MD5s of the main resource files. Dr. Brain 2 is just a dump of the contents of the floppy onto CD. LSL5 is too, but has extra content. I cannot say about LSL1VGA since I don't have the CD version of it to compare, but I always assumed that they were the same.

never knew there were LSL5 CD version, especially Island of Dr. Brain. The only CD version available are LSL6, LSL7, and LSL collection/anthology which basically all collection of past LSL games exactly like their floppy counterpart.

Hoyle Official Book Of Games Vol 3 also had a CD release. The packaging titled it as Hoyle Classic Board Games but it's really the same game. It appears to be the floppy version put on a CD. Both show as the same version in ScummVM.

They're not talkies, no. But CD versions do exist. As was mentioned, they are merely the contents of their respective floppy disks consolidated on one CD. They aren't any different or special like KQ5, SQ4, PQ4, etc.
